    2. A neck mass is very common A variety of clinical condiitons are associated with a mass in the neck Differential diagnosis Accurate diagnosis

    3. An asymptomatic solitary neck mass in the lateral aspect of the neck in an adult should be considered a metastatic lymph node until proved otherwise.

    4. Etiology Congenital Traumatic Inflammatory Neoplastic

    5. Congenital Pediatric age group Benign: thyroglossal duct cyst,branchial cleft yst cystic hygroma, hemangioma and hemangiolymphangiomma, Lateral: inflammatory or hyperplastic LN Maligant is rare: lymphoma thyroid ca or other soft tissue tumor

    6. Traumatic Rarely produce a solitary mass History Hematoma, sternomastoid tumor AVM

    7. Inflammation Sign of inflammation and tenderness Chronic : TB, mononucleosis , toxoplasomosis cat-scratch fever, Hyperplastic lymphadenopathy in AIDS

    8. Neoplastic Benign: Lipoma , neurofibromaCarotic bod y tumorn neurogenic tumor adenoma of thyroid and parathyroid. Malignant: primary or metastatic

    11. 80s simple rule for solitary neck mass If benign tumors of the thyroid glad are excluded, nearly 80% of neck mass in adults are malignant. 80% are metastatic 80% arise from primary sites above the clavicle. 80% are metastatic SCC.

    14. We can predict a potential primary site according to the location of a metastatic lymph node presenting as a solitary neck mass

    15. Diagnosis History Physical examination Fine neddle aspiration or biopsy: sensitivity , lymphoma is difficult Excional biopsy : small or movable Incisional biopsy : large , multiple unresectable.
